1. Excellent Quality

   Posted by J.G. on 4th May 2018

   I've used GM barrel blanks to machine AR barrels, bolt action target rifles, and muzzle loading rifles. I have come to the conclusion that they are extremely accurate barrels no matter what you happen to be building. You can't go wrong with GM. The concentricity between the bore and grooves is fantastic and so is the uniformity of the groove shape between each other. Never high spots protruding from the groove side into the bore. Great quality!

2. Great barrel for the price

   Posted by Austin on 19th Dec 2017

   I bought this barrel blank a while back for a replacement for my Howa Mini Action. I'm very impressed with the quality and follow up from Green Mountain. I will still continue to purchase their products and will be my first choice for replacement barrels.

3. 1.2 MOA at 600 yds!!

   Posted by Harold Howell on 15th Aug 2015

   I finally got to shoot 600 yds. Ammo used 75gr Hornady match and 75gr Tulammo. I was surprised. Both rendered 3" groups at 600 yds! I think that's pretty good.

4. Varmint Gun AR15 platform

   Posted by Harold in CO on 7th May 2015

   So I got his blank to build a long range 223. I chambered it 223 Wylde and finished it to 24.25" OAL. Rifle length gas .936 block.
   After the first 200 rounds it settled down and now it consistently hits at 1/2 MOA at 200 yards
   This is a great product.
   Buy it you won't be disappointed.
